Hello Al,

When you used wait_key just before it did you send to screen, "I am about to
   copy pathfrom and size to pathto"? And after the copy print on screen, "I just
   copied pathfrom and size to pathto and size"? Does all this jive and it still
   copies wrong? If so maybe you have to use a diff dos version for that drive. Just
   guessing.
